DETAILED DESCRIPTION OF THE EMBODIMENTS

In what follows, the present disclosure will be described in more detail with reference to appended drawings.

The suffixes “module” and “unit” for the constituting elements used in the following descriptions are assigned only for the convenience of writing the present disclosure and do not have separate meanings or roles distinguished from each other. Therefore, the “module” and “unit” can be used interchangeably.

In the present specification, target materials are biomaterials representing a specific substrate, and are interpreted as having the same meaning as analytical bodies or analytes. In the present embodiment, the target material can be an antigen. In the present specification, probe material is a biomaterial that specifically binds to a target material and is interpreted as having the same meaning as a receptor or an acceptor. In the present embodiment, the probe material can be an antibody.

The electrochemical-based biosensor combines the analytical ability of the electrochemical method with a specificity of biological recognition and detects a biological recognition phenomenon for a target material as a change in current or potential, by immobilizing or containing a material having biological specificity, i.e., probe material such as an enzyme, an antigen, an antibody, or a biochemical material, on the surface of an electrode.

Hereinafter, a biosensor system according to the present embodiment will be described with reference to FIGS. 1 and 2 .

FIG. 1 is a diagram illustrating a biosensor system according to one embodiment of the present disclosure, and FIG. 2 is a configuration diagram of a biosensor diagnostic device 200 and a biosensor cartridge 100 of FIG. 1 .

Referring to FIG. 1 , a biosensor system 10 according to one embodiment of the present disclosure comprises a biosensor diagnostic device 200, a plurality of biosensor cartridges 100, and a terminal 600. At this time, the terminal 600 can be a mobile terminal.

Meanwhile, the biosensor system 10 according to one embodiment of the present disclosure further includes at least one server 400 and one or more external terminals 300.

When the plurality of biosensor cartridges 100 are inserted, the biosensor diagnostic device 200 reads a detection signal from the biosensor cartridge 100 to read the presence or the absence of a target material.

The biosensor diagnostic device 200 is a portable integrated diagnostic device 200, detects a current change for the presence of a trace amount of a target material from the biosensor cartridge 100, and accordingly diagnoses a disease and delivers a result to a user.

To this end, the biosensor diagnostic device 200 can be provided to be portable by integrating each functional block, miniaturizing it, and integrating it in one case or within one housing.

The biosensor diagnostic device 200 can be moved regardless of location, regardless of the presence or absence of an external power source by mounting a battery 281 therein. In addition, the diagnostic device 200 includes a function of compensating a reproducibility and non-uniformity of a sensor by including a pre-processing process of correcting a detection signal from the biosensor cartridge 100 to be able to read a minute signal change.

Also, the biosensor diagnostic device 200 can include a quick response (QR) reader capable of performing authentication by reading a code image such as a QR code disposed on the rear surface of the biosensor cartridge 100 to obtain environmental information for authenticating the biosensor cartridge 100 and a communication module capable of transmitting and receiving a signal for authentication to and from an external cloud server 400.

In the biosensor diagnostic device 200, a program algorithm or application for diagnosing a disease by measuring and analyzing the detection signal from the biosensor cartridge 100 can be installed, and different algorithms are executable based on the type of each biosensor cartridge 100.

In addition, the biosensor diagnostic device 200 includes a display device 290 for directly displaying the diagnosis result to a user and is designed to be directly manipulated through a user interface 296, 297, 294.

The detailed configuration of the integrated biosensor diagnostic device 200 will be described later.

Meanwhile, the biosensor system includes a plurality of biosensor cartridges 100 which is inserted into the biosensor diagnostic device 200 to provide detection signals.

Each of the biosensor cartridges 100 is electrically connected to a diagnostic device 200 in which an algorithm capable of measuring and analyzing an electrical detection signal generated in a biosensor chip 500 is installed.

Specifically, as shown in FIG. 1 , the biosensor cartridge 100 can be inserted into and electrically connected to a cartridge insertion module 2911 of the integrated biosensor diagnostic device 200.

The biosensor cartridge 100 can accommodate the biosensor chip 500 corresponding to a biosensor device 500 in a housing 110, 120, and the housing 110, 120 can accommodate a circuit board 150 including a circuit pattern that extends to a connection terminal 153 that is connected to an electrode pad of the biosensor chip 500 and inserted into the insertion module 2911 of an external biosensor diagnostic device 200.

The housing 110, 120 can be separated into an upper housing 110 and a lower housing 120, and the upper housing 110 and the lower housing 120 are coupled and fixed while accommodating the biosensor chip 500 and the circuit board, thereby constituting a single biosensor cartridge 100 (e.g., see FIGS. 5A and 5B).

The biosensor cartridge 100 has a connection terminal 153 for physical and electrical coupling with the biosensor diagnostic device 200 exposed from one end to the outside, and a solution accommodating portion 119 for accommodating a specimen is formed on the surface of the upper housing 110.

The solution accommodating portion 119 exposes a part of the inner biosensor chip 500, and when a specimen is accommodated in the solution accommodating portion 119, the charge concentration of a channel of the biosensor chip 500 is varied according to the antigen-antibody reaction of the biosensor chip 500, so that the current flowing through the electrode of the biosensor chip 500 varies. The varied current is read by the diagnostic device 200 through the connection terminal 153.

In this situation, in order to secure the charge mobility of the biosensor chip 500, a channel can be implemented with various materials, and in particular, a channel can be implemented by using graphene.

The detailed configuration of the biosensor cartridge 100 will be described in detail later.

Meanwhile, the biosensor system can include at least one server 400.

The server 400 can be a manufacturer server 400, and the server 400 can include a processor capable of processing a program. The function of the server 400 can be performed by the manufacturer's central computer (cloud).

For example, the server 400 can be a server 400 operated by a manufacturer of the biosensor cartridge 100 and the diagnostic device 200. As another example, the server 400 can be a server 400 that is provided in a building, and stores state information on devices in the building or stores content required by home appliances in the building.

The server 400 can store firmware information and diagnostic information on the diagnostic device 200 and transmit certification information on the biosensor cartridge 100 requested from the diagnostic device 200.

The server 400 in a biosensor system can be one of a plurality of cloud servers 400 of a manufacturer and can be provided within the biosensor system while a plurality of cloud servers 400 are simultaneously included to allow access to one biosensor diagnostic device 200.

As described above, when a plurality of cloud servers 400 can simultaneously access one biosensor diagnostic device 200, the biosensor diagnostic device 200 can match the ranks with respect to the plurality of cloud servers 400 and can send a certification request sequentially from the highest priority. In this situation, if a response signal is not received from the priority server 400, a certification request can be sent to the server 400 of the next priority.

The server 400 can provide cartridge sensor information including a manufacturing history from the manufacturing stage of the biosensor cartridge 100 and sensor cartridge-specific information to the biosensor diagnostic device 200 as authentication information.

In addition, the server 400 can provide calibration data and update data for the product of a corresponding ID and can transmit to the communicating biosensor diagnostic device 200.

The server 400 can also generate and distribute an upgraded version of a program for analysis for each biosensor cartridge 100.

To this end, the server 400 can receive history information on the manufacturing date, manufacturing conditions, sensor type, test result, etc. of the biosensor cartridge 100 of a manufacturer from a manufacturing server of a separate manufacturer.

In addition, the server 400 can periodically generate and distribute an upgraded version of a program provided to each diagnostic device 200 by receiving, accumulating, and machine learning the diagnosis result values for a corresponding product.

Meanwhile, the biosensor system 10 of the present embodiment can further include a plurality of user terminals 300, but the present disclosure is not limited to the specific embodiment.

When the terminal 600 or the user terminal 300 is included in the system 10, the biosensor diagnostic device 200 or the cloud server 400 can transmit data related to a diagnosis result to the terminal 600 or the user terminal 300.

To this end, a dedicated application for the terminal 600 or the user terminal 300 can be provided from the manufacturer server 400, and various processing of diagnostic data is possible by storing and executing the application in the terminal 600 or user terminal 300.

For example, when a user is infected with the same disease for a long period of time, data processing is possible so that periodic test results can be accumulated and displayed, and the processed results can be provided to the terminal 600 or user terminal 300 through an application. Accordingly, the terminal 600 or the user terminal 300 can be able to determine the prognosis for the disease and the expected treatment time or expected recovery time.

The terminal 600 or the user terminal 300 can be, for example, a laptop, a smartphone, or a tablet on which an application is installed.

The terminal 600 or the user terminal 300 can communicate directly with the diagnostic device 200 or the server 400 through a network, and the diagnostic device 200 and the server 400 can also communicate directly through a network.

In this situation, wireless communication technologies such as the IEEE 802.11 WLAN, IEEE 802.15 WPAN, UWB, Wi-Fi, ZIGBEE, Z-wave, and BLUETOOTH can be applied to the network and can include a wireless transceiver 260 of each device (the terminal 600, the user terminal 300, and the diagnostic device 200) to apply at least one or more communication technologies.

The wireless transceiver 260 (wireless interface, or wireless communication unit) can be changed depending on the communication method of other devices (the terminal 600, the user terminal 300, and the diagnostic device 200) or the server 400 to communicate with.

As described above, in the biosensor system, the connection terminal 153 of the biosensor cartridge 100 accommodating the specimen is inserted into and electrically connected to the portable integrated biosensor diagnostic device 200 so that a detection signal is read.

The functional configuration of the biosensor diagnostic device 200 for reading the detection signal is shown in FIG. 3 .

Referring to FIG. 3 , the biosensor diagnostic device 200 includes a plurality of function modules.

Each functional module can be individually packaged and accommodated in the case of one biosensor diagnostic device 200, and a plurality of functional modules can be packaged as one module and accommodated in a case 201, 202.

The biosensor diagnostic device 200 includes a signal conversion amplifier 210, a signal filter 220, a signal converter 230, an operator 250, a wireless transceiver 260, a power supply 280, a display device 290, a Quick Response (QR) reader 270, and a sensor converter 240 (e.g., a sensor controller).

The signal conversion amplifier 210 receives firstly a detection signal transmitted from the biosensor cartridge 100 and converts and amplifies the current value of the detection signal so that the current value can be read by the biosensor diagnostic device 200.

The signal conversion amplifier 210 can have an analog circuit including a resistor that generates a voltage drop according to a changed current value which is a detection signal transmitted from the biosensor cartridge 100 and can further include an amplifying circuit that receives and amplifies such a voltage drop.

The amplified signal is transmitted to the signal filter 220 to remove noise and then transmitted to the signal converter 230. The signal converter 230 can convert the amplified analog sensing value from which the noise has been removed into a digital value for a diagnostic operation and can include an analog-digital converter (ADC) for this purpose.

As described above, the signal conversion amplifier 210, the signal filter 220, and the signal converter 230 can all be implemented as a single integrated circuit (IC) chip. Such an integrated circuit chip can correspond to a cartridge insertion module 2911 in FIG. 2 .

The sensor converter 240 (e.g., a sensor controller) can provide a reference voltage whose level is changed according to the control of the operator 250 to the connection terminal 153 of the connected biosensor cartridge 100, and the biosensor cartridge 100 receives a reference voltage having a varied level from the sensor converter 240 and flows a current value changed by a varied resistance value of channel to the connection terminal 153. The sensor converter 240 can be mounted together as a voltage level conversion circuit in the integrated circuit chip.

Meanwhile, the biosensor diagnostic device 200 includes an operator 250 (e.g., an operation controller) for controlling the operation of the diagnostic device 200 and reading a received digitized detection value.

The control of the diagnostic device 200 can include a separate controller, but it is possible to simultaneously read whether a detection value is detected and control the operation of the entire diagnostic device by executing a program stored in one controller or a processor.

In this situation, the operator 250 can be implemented as a separate integrated circuit chip and can be mounted in a main board 255.

The operator 250 can read whether there exists a target material for the detection value according to the reading program, process the result and provide the result to the display device 290. In addition, such a reading result can be transmitted to the cloud server 400, the terminal 600, or the user terminal 300 through the wireless transceiver 260.

The operator 250 can also control the operation of the diagnostic device 200 for the reading. For example, when the connection terminal 153 of the biosensor cartridge 100 is inserted into the cartridge insertion module 2911, the operator 250 can detect the insertion and transmit a QR reading command to the QR reader 270.

Accordingly, the QR reader 270 performs an operation for reading the QR code attached to the rear surface of the cartridge 100 inserted into the cartridge insertion module 211 and transmits the information back to the operator 250.

The operator 250 receives the QR information, performs a certification request to the cloud server 400 accordingly, and when certification information is received from the cloud server 400 and confirmed diagnosis as genuine, performs reading for the biosensor cartridge 100, and matches the reading result with the certification result of the biosensor cartridge 100 and processes it.

Accordingly, the operator 250 can reduce the error by minimizing the time difference of the result matching by simultaneously executing the module control of the diagnostic device 200 and the execution of the read program.

The operator 250 can include a memory card as a data storage device, a library file for diagnosing biomaterials, and an embedded system board equipped with a signal processing device.

For example, a memory card capable of storing output signal data is inserted into the embedded system board, and a system OS, driving program, library file for analysis, and the like are stored in the memory card.

In addition, signal processing for concentration analysis of biomaterials is calculated through comparison analysis with library files in the CPU of the embedded system board, and the analyzed result is stored again in the memory card. In addition, the wireless transceiver 260 can be mounted together in such an embedded system board but is not limited thereto.

The biosensor diagnostic device 200 includes a display device 290 as a user interface, and the display device 290 includes a liquid crystal display device, a touch panel, and the like to display an analyzed result detected by creating a program considering a user's convenience. As a user interface, it can include various types of terminals, dials, buttons, and the like.

A terminal 297, a dial 296, a button 294, and the like can turn on/off the operation of the biosensor diagnostic device 200 and can be connected to the operator 250 to control the operator 250 according to a user command. That is, as a user's command is input in the interface 297, 296, 294, the diagnosis of the biosensor cartridge 100 can be started, where the display device 290 displays a progress during the diagnosis process and displays a diagnosis result after the completion of diagnosis.

The biosensor diagnostic device 200 includes a separate power supply 280 capable of applying power to a plurality of modules, and the power supply 280 includes a battery 281. Accordingly, it is possible to supply power to the internal module from the battery 281 by charging an external power source, and thus the device 200 can be portable.

Meanwhile, the signal conversion amplifier 210, the signal filter 220, the signal converter 230, the sensor converter 240, and the operator 250 can be installed within the signal processor 295 implemented in the form of system-on-chip (SOC).

Meanwhile, an electrical signal from the biosensor cartridge 100 can be delivered to the signal conversion amplifier 210 within the signal processor 295 through the interface 205.

Meanwhile, an electrical signal from the sensor converter 240 within the signal processor 295 can be delivered to the biosensor cartridge 100 through the interface 205.

The cartridge insertion module 2911 protrudes from the reference plane to the front surface and includes a terminal portion to be electrically connected by inserting the connection terminal 153 of the cartridge in the Z-axis direction.

Accordingly, a terminal portion is formed in a side surface of the insertion module 2911, and the terminal portion can include at least one insertion hole 2914.

The insertion hole 2914 can be implemented in various ways depending on the shape of the connection terminal 153 of the cartridge. When the connection terminal 153 of the cartridge is formed in an SD card chip type, a USB type such as USB-A, USB-C type, or a PIN type, correspondingly, it can be formed to read an electrode of the connection terminal 153.

In addition, when the plurality of insertion holes 2914 are formed to read various types of connection terminal 153, the plurality of insertion holes 2914 can be disposed in parallel along the X-axis direction in the side surface of the insertion module 2911.

A main board 255 in which each module is mounted is disposed on the rear surface of the front panel 291, and the main board 255 can also have a shape similar to the bottom surface of the inner cover 205.

The main board 255 is divided into a display area 2551 in which the display module 295 is disposed in correspondence with the area division of the front panel 291, a cartridge area 2552 corresponding to the cartridge insertion module 2911, a QR area 2553 corresponding to the second opening 293, and a control area 254 corresponding to the button and the dial for a user interface (e.g., see FIG. 4 ).

In addition, the cartridge insertion module 2911 is provided to one side of the display module 295, and the connection terminal 153 is inserted into the insertion hole 2914 parallel to the reference plane of the panel 291, so that diagnosis of the biosensor cartridge 100 is possible.

Hereinafter, the biosensor cartridge 100 applied to the present embodiment will be described with reference to FIGS. 5 to 12 .

FIGS. 5A and 5B are top and rear views of an example of the biosensor cartridge 100 of FIG. 1 .

Referring to FIGS. 5A to 5B, the biosensor cartridge 100 according to the present embodiment accommodates a biosensor chip 500 that generates an electrical detection signal according to a target material and has a structure which includes a connection terminal 153 capable of transmitting the detection signal to an external diagnostic device 200.

Specifically, the biosensor cartridge 100 is formed of a bar type housing 110, 120, a partial surface 151 of the circuit board 150 protrudes from the end surface of the side surfaces of the housing 110, 120, and a connection terminal 153 that is inserted into the external diagnostic device 200 and transmits the detection signal is formed on the partial surface 151 of the protruding circuit board 150.

The accommodating portion 119 for accommodating a specimen is formed on an upper surface 111 of the housing 110, 120, and a QR label 160 can be attached to the lower surface of the housing 110, 120.

The connection terminal 153, which protrudes from the side surface of the housing 110, 120 and is exposed, is disposed in the same direction as the lower surface of the housing 110, 120 and is not exposed when the cartridge 100 is viewed from the upper surface. Accordingly, it is possible to reduce the risk that the specimen flowing out of the accommodating portion 119 touches the connection terminal 153.

The biosensor cartridge 100 includes housing 110, 120, a biosensor chip 500, and a circuit board 150.

The circuit board 150 is also formed in a bar type and has one end where a connection terminal 153 is formed so that the connection terminal 153 of the circuit board 150 is coupled to be exposed to the outside of the housing 110, 120, thereby forming the entire shape of cartridge 100.

Specifically, the housing 110, 120 includes a lower housing 120 and an upper housing 110.

The lower housing 120 includes a bar-type bottom surface 121 and a side surface 122 surrounding the bottom surface 121. The bottom surface 121 includes a plurality of coupling protrusion 127, 128 protruding toward the upper housing 110, and each of the coupling protrusions 127, 128 is fitted with a coupling groove of the upper housing 110 so that the upper and lower portions of the housing 110, 120 are coupled and integrated.

A substrate protrusion 127 defining a position while fixing the circuit board 150 toward the upper housing 110 is formed on the bottom surface 121 of the lower housing 120, and a plurality of sensor protrusions 126 defining a chip area 125 in which the biosensor chip 500 is disposed are formed in one side thereof.

The sensor protrusion 126 is disposed to correspond to the size of the biosensor chip 500 to define a chip area 125 in which the biosensor chip 500 is disposed and is formed to have a certain elasticity so that the biosensor chip 500 can be fitted. Each sensor protrusion 126 has a protruding structure having an inclination toward the chip area 125 so that it is not damaged by the edge of the sensor protrusion 126 when the biosensor chip 500 is mounted. However, since the sensor protrusion 126 does not electrically connect the biosensor chip 500, it can be implemented in various forms, and can be formed as a rail structure for sliding coupling in addition to fitting.

A biosensor chip 500 is disposed in the chip area 125.

The biosensor chip 500 is a semiconductor-based biosensor and is divided into a sensor area 530 that reacts according to a target material in the specimen through contact with the specimen, and a pad area 510 for transmitting a detection signal generated according to the sensor area 530 to the circuit board 150.

The pad area 510 can be patterned to be disposed in one side of the biosensor chip 500, and accordingly, the electrical connection between the circuit board 150 and the biosensor chip 500 is performed in the pad area 510.

The biosensor chip 500 can have different sizes depending on the size of the cartridge, for example, can have a rectangular shape of 8 mm×6 mm, or can have a square shape of 6 mm*6 mm. The size of the biosensor chip 500 can be variously implemented according to the performance of the biosensor chip 500 or the purpose of the biosensor chip 500.

The detailed structure of the biosensor chip 500 will be described in detail later.

The circuit board 150 is disposed on the biosensor chip 500.

The circuit board 150 can be provided as a rigid board like a printed circuit board (PCB) board, and the biosensor chip 500 is electrically/physically bonded to the lower portion.

The circuit board 150 includes a sensor opening 155 through which a sensor area 530 of the biosensor chip 500 is exposed, and the sensor opening 155 has a size smaller than that of the biosensor chip 500. In addition, the opening 155 can have a size corresponding to the sensor area 530 of the biosensor chip 500 and has a size to expose the sensor area 530.

The circuit board 150 further includes a protrusion hole 154 through which the substrate protrusion 127 of the lower housing 120 penetrates to fix the circuit board 150, and accordingly, the circuit board 150 and the lower housing 120 are fixed.

The circuit board 150 can be implemented by a plurality of circuit patterns patterned on a base member (not classified by reference numerals, denoted by 150 in the drawing) as the deposition structure thereof, and an insulating layer covering the circuit pattern.

The circuit pattern and the insulating layer can be formed on a rear surface of the base member, and a reinforcing plate can be attached to the front surface of the base member. A rear surface of the circuit board 150 can be defined as a surface facing the lower housing 120, and a front surface of the circuit board 150 can be defined as a surface facing the upper housing 110.

The required strength at the time when a part of the circuit board 150 is used as the connection terminal 153 that is inserted into the diagnostic device 200 can be satisfied by attaching the reinforcing plate to the rear surface of the circuit board 150 as described above.

On the rear surface of the circuit board 150, a circuit pattern including a plurality of connection pads 158 for connecting to the biosensor chip 500 is formed, and a circuit pattern that extends to the connection pad 158 to transmit the detection signal from the connection pad 158 to the external diagnostic device 200 is formed to be connected to the connection terminal 153 of the front surface.

Accordingly, the number of connection terminals 153 of the circuit board 150 can be equal to or larger than the number of pads of the biosensor chip 500.

The plurality of connection terminals 153 can be spaced apart from each other at one end of the exposed surface 151 of the circuit board 150, i.e., at one end of the circuit board 150 and disposed in parallel.

For example, when the biosensor chip 500 has three pads, the number of the connection pads 158 of the circuit board 150 also satisfies three, and the number of the connection terminal 153 satisfies three or more.

The connection terminal 153 further includes terminals not electrically connected to each connection pad 158 and can be used as a terminal for electrostatic discharge (ESD) blocking.

The circuit pattern patterned on the rear surface of the circuit board 150 can include eight connection terminals 153. In such a connection terminal 153, when the biosensor chip 500 is driven in multi-channel to be connected to a plurality of connection pads 511 and to transmit and receive signals, six connection terminals can be allocated as a connection terminal 153 for transmitting and receiving signals of each pad by connecting to the source pad, drain pad, and gate pad of the biosensor chip 500 corresponding to each channel, and two connection terminals are applicable as a terminal for ESD and incoming detection signal generation.

Such a connection terminal 153 can be formed as a USB-A type depending on an embodiment, but a USB-C type having more terminals as shown in FIG. 1 can also be utilized.

Also, the connection terminal 153 can be implemented as a pin type, and more terminals can be implemented.

Thus, the number of pads of the connection terminal 153 can increase in proportion to the number of probe material applied to the biosensor chip 500, e.g., the number of source electrodes (or the number of drain electrodes).

Meanwhile, the circuit board 150 includes a plurality of coupling grooves, and the plurality of coupling grooves are formed to be able to fit while specifying a position when the upper housing 110 and the lower housing 120 are coupled.

Meanwhile, the upper housing 110 has a structure where the upper surface 111 and the rear surface are different from each other.

The upper housing 110 faces the lower housing 120 and is coupled to the lower housing 120 and serves as an upper case capable of accommodating the circuit board 150 and the biosensor chip 500 therein. In addition, an accommodating portion 119 exposing the sensor area 530 of the biosensor chip 500 is formed in the upper housing 110 to accommodate a test target specimen.

The upper housing 110 is formed to have rigidity that can firmly support the connecting member 140 by pressing the connecting member 140 with a certain force.

The upper housing 110 and the lower housing 120 can be configured to surround the surfaces of the biosensor chip 500 and the circuit board 150 to protect the biosensor chip 500 and the circuit board 150 from the outside. Due to the strong coupling between the upper housing 110 and the lower housing 120, the specimen provided to the biosensor chip 500 through the accommodating portion 119 can be prevented from leaking into the housing 110, 120.

At this time, when the upper housing 110 and the lower housing 120 are coupled, an opening through which the connection terminal 153 of the circuit board 150 protrudes is formed in one side of the side surface, e.g., in a cross-section, so that the connection terminal 153 is exposed to a cross-section and is inserted into the insertion hole 2914 of the external diagnostic device 200 as the connection terminal 153 of the cartridge.

The accommodating portion 119 for exposing the sensor area 530 of the biosensor chip 500 and accommodating a specimen is formed on the upper surface 111 of the upper housing 110. The accommodating portion 119 is a space for inducing a reaction with the exposed sensor area 530 by accommodating a test target specimen in a fluid state, e.g., in a liquid state, and the accommodating portion 119 forms a conical channel (e.g., a funnel shape) whose diameter becomes narrower as it approaches the sensor area 530 from the upper surface 111.

FIG. 6 is one example of an internal block diagram of a mobile terminal of FIG. 1 .

Referring to FIG. 6 , the mobile terminal 600 can include a wireless transceiver 610, an Audio/Video (A/V) input device 620, a user input device 630, a sensing device 640, an output device 650, a memory 660, an interface 665, a controller 670 (e.g., a processor), and a power supply 690.

The NFC module 617 can perform short-distance magnetic-field communication. When the NFC module 617 approaches within a predetermined distance from an NFC tag or a home appliance equipped with an NFC module, that is, when tagging is performed, the NFC module 617 can receive data from the corresponding home appliance or transmit data to the corresponding home appliance.

Besides, short-distance communication technology can use Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZIGBEE, and the like.

The user input device 630 generates key input data entered by the user to control the operation of the terminal. To this end, the user input device 630 can include a keypad, a dome switch, and a touchpad (static pressure/capacitance). In particular, when the touchpad forms a layer structure with the display 680, it can be referred to as a touch screen.

The sensing device 640 detects the current state of the mobile terminal 600, such as the open/closed state of the mobile terminal 600, the position of the mobile terminal 600, and the presence or absence of user contact to generate a sensing signal for controlling the operation of the mobile terminal 600.

The sensing device 640 can include a detection sensor 641, a pressure sensor 643, and a motion sensor 645.

For example, the specimen can refer to saliva, a body fluid including sweat, blood, a solution diluted with serum or plasma, and the like, as a biological material.

The biosensor chip 500 is a semiconductor-based biosensor chip 500 and can be manufactured as a biosensor chip 500 to which graphene is applied.

The biosensor chip 500 can have various sizes depending on the type of target material, the number of target materials, and the size of the cartridge 100 and can be designed to have a size of, for example, 6×6 mm or 6×8 mm.

Referring to FIG. 7 , the biosensor chip 500 according to the present embodiment can have a rectangular shaped plane, have a front surface on which a sensor area 530 exposed to the outside through the accommodating portion 119 is formed, and be partitioned into a pad area 510 which is spaced apart from the sensor area 530 and connected to the pad 158 of the circuit board 150 through the connecting member 140 and a connection portion 520 connecting the sensor area 530 and the pad area 510.

A probe material, for example, an antigen, an antibody, and an enzyme, which detects a target material from a contacted specimen and reacts with the target material to generate an electrical signal, is attached to the sensor area 530.

When the sensor area 530 comes into contact with a specimen, it interacts with a target material included in the specimen to generate an electrical signal. Accordingly, the external diagnostic device 200 connected to the biosensor 100 can analyze an electrical signal generated from the biosensor 100 to detect the presence or concentration of the target material.

The sensor area 530 includes a transistor structure, and has a structure where probe material is attached to a channel area 550 of the transistor.

Specifically, the sensor area 530 includes a plurality of circular or ring-shaped electrodes 535S, 535D, and 535G forming a concentric circle, and a plurality of channel areas 550 are formed between the plurality of electrodes 535S, 535D, and 535G, particularly, between the source electrode 535S and the drain electrode 535D.

An insulating layer is formed on the semiconductor substrate, and the insulating layer can be formed of oxide or nitride. When the semiconductor substrate is a silicon substrate, the insulating layer can be formed of silicon oxide or silicon nitride and can be formed by various methods. For example, a silicon oxide layer can be formed on the surface through heat treatment.

A plurality of channels 533 are formed on the insulating layer to be spaced apart from each other.

A plurality of channels 533 are disposed by being spaced apart by a predetermined distance from the circle center O of the sensor area 530, and a central area is exposed to form the channel area 550.

The plurality of channels 533 are disposed by being spaced apart from each other on the circumference of an imaginary circle having a radius of a predetermined distance from the center O of the circle. For example, the plurality of channels 533 can be arranged similar to spokes on a wheel.

The plurality of channels 533 can be disposed to be spaced apart by the same angle; for example, as shown in FIG. 7 , seven channels 533 can be formed, and each channel 533 can be spaced apart from the others at an angle of 45 degrees.

Alternatively, five channels 533 can be disposed so that each channel 533 can be spaced apart at an angle of 60 degrees.

One channel 533 can be patterned in a specific shape and can be formed by a semiconductor material but can also be formed by a graphene-based material that is highly reactive as a highly conductive material.

The channel 533 includes an area overlapping with the source electrode and the drain electrode 535S, 535D and a channel area 550 exposed to the outside through the accommodating portion 119 between two overlapping areas.

The channel area 550 can have lower resistance in the channel area 550 as the channel 533 is formed in a dumbbell shape or an I-shape to have a narrower width than the overlapping area as shown in FIG. 7 but is not limited to the specific situation; instead, the channel area 550 can be formed in a bar type to have the same width from the overlapping area to the channel 533.

A source electrode 535S having the shape of the smallest circle can be formed at the center O of the circle of the sensor area 530. The source electrode 535S can be formed to have the smallest diameter and to overlap one end of the channel 533; the source electrode 535S simultaneously overlaps a plurality of channels 533 and applies a source voltage simultaneously to a plurality of channels 533.

A drain electrode 535D can be formed outside the channel area 550 to be spaced apart from the source electrode 535S.

The drain electrode 535D can be formed in a ring shape and is formed along the circumference of an imaginary circle that surrounds the channel area 550 and has a larger diameter than that of the channel area 550.

The drain electrode 535D can also overlap the plurality of channels 533 simultaneously to receive current from the plurality of channels 533 simultaneously.

One end of the drain electrode 535D is cut to form a passage through which the connection portion 521 of the source electrode 535D passes (e.g., forming a cut area or a notched area). For example, a connection portion of the source electrode 535S passes through the cut area in the notched ring shape of the drain electrode 535D. In other words, when viewed from above in a plan view, the drain electrode 535D and the source electrode 535S can form coupled arrangement similar to a ball and socket joint.

A gate electrode 535G is formed along the circumference of an imaginary circle having a larger diameter surrounding the drain electrode 535D.

The gate electrode 535G can have the largest area and occupy ½ to ⅔ of the sensor area 530. The gate electrode 535G is formed to be spaced apart from the source electrode, the gate electrodes 535S and 535D, and the channel area 550.

The gate electrode 535G also forms a passage so that the connection portions 521 of the grain electrode and the source and drain electrodes 535S and 535D are connected to the pad 511, and one end of the gate electrode 535G is disconnected. For example, the gate electrode 535G can also include a cut out area or a notched portion (e.g., a “C” shape) for wiring connections to the source and drain electrodes 535S and 535D. For example, the gate electrode 535G can have a letter “C” shape in which both of the connection portions 521 of the source electrode and the drain electrode 535S, 535D can fit into the opening or mouth of the letter “C” shape.

The electrodes 535S, 535D, and 535G of the sensor area 530 designed as shown in FIG. 7 are formed in the same layer.

Accordingly, the source electrode, the drain electrode, and the gate electrodes 535S, 535D, and 535G are all formed in the same layer and formed in one process.

For example, the source electrode, the drain electrode, and the gate electrode 535S, 535D, and 535G can be respectively formed by forming an electrode layer (e.g., a same metal layer) and simultaneously patterning a corresponding electrode layer.

Thus, a process step can be reduced, and a process time and cost can be reduced by simultaneously forming three electrodes 535S, 535D, and 535G that do not overlap each other.

The metal layer can be formed of at least one of Ni, Zn, Pd, Ag, Cd, Pt, Ga, In, and Au, but is not limited thereto.

A passivation layer 536 is formed on the electrodes 535S, 535D, and 535G.

The passivation layer 536 is formed on the entire biosensor chip 500 to protect the sensor area 530 and the electrodes 535S, 535D, and 535G.

The passivation layer 536 can be formed of a material resistant to moisture and can be formed of, for example, an oxide layer, a nitride layer, or a carbide layer.

In addition, the passivation layer 536 can be applied with a polymer resin but is not limited thereto.

The passivation layer 536 exposes only the upper portion 551 of the plurality of channel areas 550, the gate electrode 540, and the plurality of pads 511 in the biosensor chip 500; and covers all other areas.

Accordingly, the area exposed by the passivation layer 536 is very limited.

In particular, in the sensor area 530, only the gate electrode 535G and the channel area 550 are exposed to induce a reaction by directly contacting the specimen.

In the pad area 510, each pad 511 is exposed in an insulated state, and electrically in contact with each pad 158 of the circuit board 150 through a connecting member through an upper connecting member 140.

As shown in FIG. 8A, probe material 610 is attached to each of the channel areas 550 exposed as described above to activate the sensor.

The probe material 610 is a material that reacts specifically to a target material to be detected by the sensor. When the target material is an antigen, an antibody can be attached thereto, or when the target material is an antibody, an antigen can be attached thereto.

When the channel 533 is formed of graphene, a linker material can be attached for smooth connection between the probe material 610 and graphene, and a process of attaching the probe material 610 after attaching a linker material on graphene is defined as an activation process.

The linker material is different depending on the material constituting the channel 533 and the probe material 610, and in the situation of graphene, it can be a polymer structure having a nano size, for example, can be formed of at least one of polyurethane, polydimethylsiloxane, Norland Optical Adhesives NOA, epoxy, polyethylene terephthalate, polymethyl methacrylate, polyimide, polystyrene, polyethylene naphthalate, polycarbonate, and combinations thereof.

In addition, the linker material can be formed of a combination of polyurethane and NOA (e.g., NOA 68). However, the linker material is not limited thereto, and can be made of various polymers having flexibility.

An electrical detection signal according to a reaction of the biosensor chip 500 can be described with reference to FIGS. 8A and 8B.

When the target material does not exist in the specimen as shown in FIG. 8A, the source electrode 535S receives a source voltage and the gate electrode 535G receives a gate voltage by the voltage applied to each pad 511.

The gate electrode 535G is exposed to the accommodating portion 119 and comes into contact with the specimen provided from the outside to apply a bias voltage to the specimen. Therefore, the specimen exists in a state of being partially charged with respect to the voltage of the gate electrode 535G.

At this time, the drain current Ids read from the drain electrode 535D is as shown in FIG. 8C.

That is, when there is no target material reacting with the probe material 610 in the specimen 600, the drain current Ids has a first value I1, which is defined as a reference current.

At this time, as shown in FIG. 8B, when the target material 650 does exist in the specimen 600, the channel 533 is charged with a specific carrier as the target material 650 reacts with the probe material 610. For example, as shown in FIG. 8B, a depletion state in which charges are accumulated in the channel 533 can proceed.

Accordingly, as the drain current Ids read from the drain electrode 535D increases, it has a second value I2 of FIG. 8C, thus indicating a positive reading for the presence of the target material 650.

At this time, the amount of accumulated charge is proportional to the area of the channel 533. Thus, when the number of channel 533 is one, the drain current IDS has a second value I2. When the number of channels 533 is two or more, the drain current IDS has a third value I3 greater than the second value I2. When the number of channels 533 is three or more, the drain current IDS has a value greater than the third value I3, thus indicating a positive reading for the presence of the target material 650. Accordingly, the value of the drain current IDS read from the drain electrode 535D is amplified by the multiple channels.

At this time, even when one channel 533 does not operate (e.g., if one channel is defective) as the plurality of channels 533 are spaced apart from each other, the existence of the target material can be recognized by causing the drain current IDS to increase or decrease in other channels 533. Thus, redundancy can be provided by the multiple channels.

As described above, the graphene channel biosensor chip 500 has a multi-channel structure having a plurality of channels spaced apart from each other, thereby amplifying a drain current and compensating for a malfunctioning channel.

In such a biosensor chip 500, both the gate electrode 535G and the channel area 550 can be exposed by the distal end opening of the accommodating portion 119 having a circle larger than the circumference of the gate electrode 535G.

In addition, the plurality of channel areas 550 are formed to be spaced apart at the same angle and at the same distance from the center O of the sensor area 530 opened by the accommodating portion 119 such that the specimen is uniformly contacted and formed in a shape surrounding the source and drain electrodes 535S and 535D in order to dispose the channel 533 between the source and drain electrodes 535S and 535D, thereby optimizing a structure.

FIG. 7 shows electrode connection portion 521 connected from one end of each electrode 535S, 535D, and 535G to the pad 511; since each electrode connection portion 521 is made of the same metal layer as the electrodes 535S, 535D, and 535G, the connection portions do not overlap each other.

FIG. 7 illustrates a situation in which the pad 511 is formed in a line on one end of the biosensor chip 500, but the present disclosure is not limited to the specific situation.

The design of the biosensor chip 500 can be variously changed as long as the transistor in which the gate electrode 535G and the plurality of channels 533 are exposed is maintained in the accommodating portion 119.

Accordingly, the position of the pad 511 can also be variously changed. However, the positions of the connecting member 140 and the connection pad 158 of the circuit board 150 are also changed according to the change in the position of the pad 511.

FIG. 9 is a coupling diagram in which the biosensor cartridge 100 is coupled to the biosensor diagnostic device 200 in the biosensor system of FIG. 1 .

As shown in FIG. 9 , when a test target specimen is received in the accommodating portion 119 of the biosensor cartridge 100 in the biosensor system 10 according to the present embodiment, the connection terminal 153 of the biosensor cartridge 100 is inserted into the insertion hole 2914 of the cartridge insertion module 2911 of the biosensor diagnostic device 200.

As described above, the specimen can be a body fluid such as saliva or sweat, or blood.

When a plurality of insertion holes 2914 are disposed, the connection terminal 153 is inserted into the corresponding insertion hole 2914 of a type matching the type of the connection terminal 153.

The insertion of the cartridge connection terminal 153 can be performed in the same manner as the insertion of the USB memory as the cartridge connection terminal 153 is similar to the USB terminal.

As described above, when the biosensor cartridge 100 and the biosensor diagnostic device 200 are coupled for analysis, the state shown in FIG. 9 is maintained.

That is, the accommodating portion 119 in which the test targeting specimen is accommodated is located outside the diagnostic device 200 and transmits an electrical signal in a state in which only the connection terminal 153 is inserted into the diagnostic device 200 through the insertion hole 2914.

The rear surface 129 of the lower housing 120 of the cartridge 100 faces the front panel 291, the QR label 160 attached to the rear surface 129 of the lower housing 120 is aligned with the QR opening 293 of the front panel 291, and the QR reading module 271 is turned on so that the camera reads the QR code of the QR label 160 of the rear surface 129 of the cartridge 100 on the QR opening 293. For example, a camera can be located under the end portion of the cartridge 100 for reading the QR code.

The operator 250 decodes the QR information to extract sensor information stored as QR information. In this situation, the sensor information can include the biosensor chip 500 type, linker information, probe material information, product ID, board ID, manufacturer information, manufacturing date, assembly date, expiration date, test date, manufacturing number, and the like.

The operator 250 can perform a certification of the biosensor cartridge 100 by at least one cloud server 400 connectable through the wireless communication module 261.

When the biosensor cartridge 100 is genuine, the correction data is downloaded from the cloud server 400 (S60), the cartridge insertion module 2911 is driven to read the detection signal of the cartridge connection terminal 153 from the sensor converter 240, the signal conversion amplifier 210, and the signal filter 220.

At this time, the gate voltage and the source voltage are transmitted to the cartridge 100 through the sensor controller 260, and the drain current that is changed accordingly is read from the signal conversion amplifier 210.

Such read drain current value is amplified, and digitized after noise is removed, and transmitted to the operator 250.

A detection signal is decoded by executing a stored algorithm with respect to the drain current value which is the transmitted digitized detection signal, thereby reading whether the target material exists in the specimen currently accommodated in the cartridge 100.

At this time, the operator 250 downloads the correction data for a corresponding cartridge from the cloud server 400 after genuine product certification, and accordingly upgrades a corresponding algorithm, so that the optimized algorithm for the accumulated results of the same type of cartridge can be applied to the analysis.

The operator 250 reads the detection signal by performing the upgraded algorithm and transmits the result to the display module 295 for visualization or display.

In addition, it can operate to transmit a corresponding reading result to the cloud server 400, and transmit to a connected terminal 600 or user terminal 300, so that a user can be notified by a designated terminal 600 or user terminal 300.

The biosensor is not easy to determine whether it is an imitation. Even if it is genuine, sensor errors are often found from test data accumulated after manufacturing and sales. Therefore, a process of classifying the biosensor cartridge 100 in which an error has occurred is required before the test proceeds.

The biosensor system of the present embodiment can check an error including a current risk to a corresponding type of the biosensor cartridge 100 through such a certification procedure.

In addition, as the insertion of cartridge 100 and the genuine product certification are performed simultaneously, certification is performed by using a separate QR reader, and then the certified cartridge is applied to the diagnostic device 200 so that two-step operation of diagnosis can be merged into one operation. Therefore, the user's convenience is increased, and the genuine product certification of cartridge and the cartridge diagnosis are performed almost simultaneously and proceeded in a state where the cartridge inserted, so that the diagnosis result of a corresponding cartridge and the information of the cartridge are not mixed and can be clearly matched.

FIG. 10 is a flowchart illustrating a method for operating a biosensor system according to one embodiment of the present disclosure, and FIGS. 11A to 14D are diagrams referenced to describe the operation method of FIG. 10 .

First, referring to FIG. 10 , the mobile terminal 600 according to one embodiment of the present disclosure includes a display 680, a camera 621 capturing a code image (e.g., QR code) of a biosensor cartridge 100, and a wireless transceiver performing wireless communication with the server 400 or the biosensor diagnostic device 200.

Meanwhile, the controller 670 of the mobile terminal 600 according to one embodiment of the present disclosure executes a diagnosis application based on an input signal S1010.

Accordingly, as shown in FIG. 11A, the controller 670 of the mobile terminal 600 can display the diagnosis application screen 1100.

Meanwhile, the controller 670 can activate the camera 621 after the diagnosis application is executed and control to capture the code image of the biosensor cartridge 100 through the activated camera 621. Accordingly, it is possible to provide a diagnosis result promptly and accurately.

Meanwhile, to proceed with the diagnostic process, the camera 621 can capture a code image of the biosensor cartridge 100, as shown in FIG. 11B S1012 (e.g., the mobile terminal 600 can take a picture of a QR code on the back of the biosensor cartridge 100).

The controller 670 of the mobile terminal 600 can control the display 680 to display the code image 1105 of the sensor cartridge 100 captured by the camera 621, as shown in FIG. 11B.

Meanwhile, the controller 670 of the mobile terminal 600 can extract information related to the captured code image 1105 from the captured code image 1105 of the sensor cartridge 100.

Next, the controller 670 of the mobile terminal 600 can control the display 680 to display diagnosis guide information after the code image is captured S1014.

The diagnosis guide information can include coupling guide information 1135 of the biosensor cartridge, face photographing guide information 1110, specimen collection guide information 1120, collection solution use information 1125, and biosensor cartridge use information 1130.

FIG. 11G illustrates a situation in which the coupling guide information 1135 of the biosensor cartridge is displayed on the display 680 of the mobile terminal 600.

Referring to the figure, when displaying the coupling guide information 1135 of the biosensor cartridge, the controller 670 of the mobile terminal 600 can display the coupling guide image 1138 of the biosensor cartridge 100 and the biosensor diagnostic device 200 together.

On the other hand, after displaying the coupling guide information 1135 of the biosensor cartridge, the controller 670 of the mobile terminal 600 can display an image illustrating a situation in which a base solution is injected into the biosensor cartridge 100.

The base solution is different from a collection solution, and by guiding the base solution to be injected into the biosensor cartridge 100 before the collection solution, it is possible to assess a difference between signals sensed by the biosensor diagnostic device 200 when the base and collection solutions are injected, respectively.

FIG. 11C illustrates a situation in which the face photographing guide information 1110 is displayed on the display 680 of the mobile terminal 600.

Referring to the figure, the controller 670 of the mobile terminal 600 can display photographing guide information to obtain a face image of a specimen collector after a code image is captured.

Then, while the photographing guide information is displayed, the controller 670 of the mobile terminal 600 can display the captured image 1112.

At this time, to obtain a face image correctly, the controller 670 of the mobile terminal 600 can control the face contour line 1114 to be displayed in the captured image 1112.

FIG. 11D illustrates that the specimen collection guide information 1120 is displayed on the display 680 of the mobile terminal 600.

Referring to the figure, the controller 670 of the mobile terminal 600 can display guide information for collecting a specimen using a cotton swab after the code image is captured.

Then, the controller 670 of the mobile terminal 600 can display the captured face image while the specimen collection guide information 1120 is displayed.

At this time, to collect a specimen correctly, the controller 670 of the mobile terminal 600 can control the swab guide line CBJ to be displayed in the captured face image.

On the other hand, when the position of a swab within the captured face image does not reach a reference position while the specimen collection guide information 1120 is displayed, the controller 670 of the mobile terminal 600 can display specimen re-collection guide information. Accordingly, the specimen collection process can be guided in detail. In this way, even an inexperienced layperson can be guided through the process of collecting a proper specimen.

FIG. 11E illustrates a situation in which the display 680 of the mobile terminal 600 displays the collection solution use information 1125.

Referring to the figure, the controller 670 of the mobile terminal 600 can control a collection solution image 1128 to be displayed together when the collection solution use information 1125 guiding a user on how to shake the collection solution is displayed. Accordingly, it is possible to guide the specimen collection process in detail.

FIG. 11F illustrates a situation in which the biosensor cartridge use information 1130 is displayed on the display 680 of the mobile terminal 600.

Referring to the figure, when the biosensor cartridge use information 1130 is displayed, the controller 670 of the mobile terminal 600 controls the collection solution injection image 1133 for guiding how to inject the collection solution to be displayed together. Accordingly, it is possible to guide the specimen collection process in detail.

To summarize FIGS. 11C to 11G, after capturing the code image 160 of the biosensor cartridge 100, the controller 670 of the mobile terminal 600 can control the coupling guide information 1135 of the biosensor cartridge, face photographing guide information 1110, specimen collection guide information 1120, specimen solution use information 1125, and biosensor cartridge use information 1130 to be displayed sequentially on the display 680. Accordingly, it is possible to guide the specimen collection process in detail, which can make the process easy and accurate, even when carried out by a layperson.

Next, after the S1014 step of FIG. 10 , the biosensor diagnostic device 200 captures a code image S1015 (e.g., a picture of the QR code).

The wireless transceiver 610 of the mobile terminal 600 can transmit information related to the code image S1016.

In response to the transmission, the server 400 can receive information related to the code image S1018.

Meanwhile, the biosensor diagnostic device 200 can transmit the captured code image and information related to the code image to the server 400 S1020.

In response to the operation above, the server 400 can receive information related to the code image from the biosensor diagnostic device 200 S1021.

Meanwhile, the wireless transceiver 610 can transmit mobile terminal 600 information to the server 400 together when transmitting information related to the captured code image 1105. Accordingly, exposure of personal information can be minimized.

The server 400 matches information related to the code image from the mobile terminal to the information related to the code image from the biosensor diagnostic device 200 to determine whether they are the same.

Then, when the information related to the code image from the mobile terminal matches the information related to the code image from the biosensor diagnostic device 200, the server 400 transmits authentication information to the biosensor diagnostic device 200 S1023.

Accordingly, the biosensor diagnostic device 200 receives the authentication information from the server 400 S1025.

Then, the biosensor diagnostic device 200 supplies current to the coupled biosensor cartridge 100, senses the current flowing through the biosensor cartridge 100, and detects a change in current S1028.

Then, the biosensor diagnostic device 200 transmits diagnosis result information based on the current change to the server 400 S1030. In response to the transmission, the server 400 receives diagnosis result information S1032.

Meanwhile, the server 400 transmits the diagnosis result information to the mobile terminal 600 S1035. In response to the transmission, the mobile terminal 600 receives the diagnosis result information S1037. Accordingly, it is possible to provide a diagnosis result promptly and accurately.

Meanwhile, when the diagnosis result information received from the server 400 corresponds to confirmed diagnosis result information (e.g., a positive diagnosis result, such as indicating that the user is infected or the specimen includes the target material), the controller 670 of the mobile terminal 600 collects movement location information and movement time information S1040.

Then, the wireless transceiver 610 of the mobile terminal 600 transmits the collected movement location information and movement time information of the mobile terminal 600 and/or the user to the server 400 S1043. In response to the transmission, the server 400 receives the movement location information and movement time information from the mobile terminal 600 of a confirmed case S1045.

Accordingly, it is possible to promptly and concisely obtain information on the movement location of the confirmed case. Also, when the diagnosis result information is the confirmed diagnosis result information, it is possible to obtain the movement location information while minimizing exposure of personal information. For example, in this way, the whereabouts and travels of a user (e.g., and his or her mobile terminal) who is confirmed to be infected can be accurately tracked and reported for contact tracing purposes and for notifying others of possible exposure.

Meanwhile, the wireless transceiver 610 of the mobile terminal 600 can further transmit personal information and call list information to the server 400 when diagnosis result information received from the server 400 corresponds to confirmed diagnosis result information. Accordingly, it is possible to minimize exposure of personal information.

FIG. 12A illustrates a situation in which information related to a capture code image Icde is transmitted to the server from the mobile terminal 600.

FIG. 12B illustrates a situation in which, when a connection terminal 153 of the biosensor cartridge 100 is coupled to the interface 205 of the biosensor diagnostic device 200, a capture code image or information Infa corresponding to the captured code image is transmitted to an external server 400.

The external server 400 can receive the captured code image or the information Infa corresponding to the captured code image and perform authentication through comparison with internal data.

When authentication is completed, the external server 400 can transmit the authentication information Infb, as shown in FIG. 12B. In response to the transmission, the wireless transceiver 260 of the biosensor diagnostic device 200 can receive the authentication information Infb, as shown in FIG. 12B.

Meanwhile, when the biosensor diagnostic device 200 receives the authentication information Infb from the server 400, the signal processor 295 within the biosensor diagnostic device 200 can control a diagnosis procedure to be performed.

For example, when the authentication information Infb is received from the server 400, the interface 205 can output an electrical signal Sga of a first level Lva to the biosensor cartridge 100 through the interface 205 during a first period PTa, as shown in FIG. 12C.

In response to the operation above, the biosensor cartridge 100 can receive the electrical signal Sga of the first level Lva.

FIG. 12F illustrates a situation in which an electrical signal Sga of the first level Lva is output to the biosensor cartridge 100 from the biosensor diagnostic device 200 at the first time point T1, which is the start time point of the first period PTa.

Meanwhile, the biosensor cartridge 100 can apply the electrical signal Sga of the first level Lva to at least one of the electrodes 535S, 535D, 535G of the sensor area 530.

And the biosensor cartridge 100 can output the electrical signal Sgb of the second level Lvb flowing through at least one of the electrodes 535S, 535D, 535G of the sensor area 530 during the second period PTb after the first period PTa.

In response to the above operation, the biosensor diagnostic device 200 can receive the electrical signal Sgb of the second level Lvb, as shown in FIG. 12F.

FIG. 12D illustrates an example in which the electrical signal Sgb of the second level Lvb is output to the biosensor diagnostic device 200 from the biosensor cartridge 100 at the second time point T2 which is the start time point of the second period PTb.
